Question

Graph ​ g(x)=2cosx ​.

Use 3.14 for π .

Use the sine tool to graph the function. Graph the function by plotting two points. The first point must be on the midline and closest to the origin. The second point must be a maximum or minimum value on the graph closest to the first point.

Answer 1

the correct one is the yellow line i took the test and the yellow one is right so graph it on 0, and 1.57 2

Explanation:

Answer 2

we can draw the graph of cosine with amplitude 2.

Explanation:

In the given function g(x) = 2cosx we know the following parameters which are helpful to draw the graph.

Its a cosine graph given in the form of y = acos(Bx + c) + d

Here a is amplitude, period =
`(2\pi )/(B)`, c = phase shift, d = vertical shift

We know a = 2, B =
`(2\pi )/(1)`, c = 0, d = 0.
